In FIG. 1 the reference character 10 designates generally a singlesheath box car. It may be employed either as part of railroad rollingstock or as a part of a truck body. The box car 10 is provided with sidewalls 11 of sheet steel which are reinforced by vertical channel shapedside posts 12 that are welded to the outer side of the side walls 11 inaccordance with conventional construction. The box car 10 is illustratedas containing lading, indicated generally at 13, which may be in theform of boxes, barrels and other containers. It is desirable to hold thelading 13 against longitudinal movement in the box car 10 resulting fromforces incident to acceleration and deceleration. For this purpose beltrails 14 are provided at various elevations on the inner sides of theside walls 11 in aligned relation. The belt rails 14 have openings 15 atspaced locations therealong for receiving, locating and locking pins 16,FIG. 1a, that project from fittings 17 that are located at the ends oftelescoping cross members that are indicated, generally, at 18. Thefittings 17 have hook portions 19 which are arranged to overlie theupstanding flange 20 of the belt rail 14 as shown in FIG. 6.

Referring now particularly to FIGS. 2-14 it will be observed that theside wall 11 is deformed as indicated at 23 into the respective sidepost 12 to provide a lading tie receiving section having a bottom wall24, inclined side walls 25 and inclined end walls 26. It will beunderstood that these deformations as indicated at 23 are located inhorizontal and vertical aligned relation in the side walls 1 1. They areprovided for receiving lading tie anchors 27 which have projections 28extending rearwardly therefrom and engaging the bottom wall 24. Asindicated at 29 the lading tie anchors 27 are welded to the side walls25. Each lading tie anchor 27 has a central section 30 for receiving alading tie that is illustrated by broken lines at 31 in FIG. 3.

It is desirable in many instances to utilize the already present ladingtie anchors 27 for mounting the belt rails 14. It is then only necessaryto make a slight modification in the existing lading tie anchors 27 aswill appear hereinafter.

Referring particularly to FIGS. 6 and 7 it will be observed that thelading tie anchor 27 has a belt rail support, indicated generally at 34,detachably mounted thereon. The belt rail support 34 preferably is inthe form of a J-shaped steel plate having a hook portion 35 whichoverlies the upper end 36 of the lading tie anchor 27. The lower end ofthe belt rail support 34 may be provided with an opening 37 forreceiving a bolt 38 that is threaded into a threaded opening 39 in thelower end of the lading tie anchor 27.

The belt rail 14, which extends along the inner side of the side wall 11is spaced slightly from the outer surface of the belt rail support 34,as seen in FIG. 6, and is welded thereto as indicated at 40. It will beunderstood that the lading tie anchors 27 are positioned in alignedrelation horizontally and vertically along the inner side of the sidewalls 11. One or more belt rails 14 are welded, as indicated at 40, tothe belt rail supports 34 in place of the lading tie anchors 27. In thismanner the belt rail supports 34 are accurately located with respect tothe lading tie anchors 27. Shoulders 41 integral with the anchor 27 areengageable by the sides of the belt rail support 34 to resistlongitudinal shock forces. It will be understood that the belt rails 14can be removed as a unit with the belt rail supports 34 welded theretoin the event that it is desirable to em ploy the lading tie anchors 27in conjunction with lading ties 31.

FIGS. 8 and 9 illustrate how a Huck bolt pin 43 can be employed forsecuring each belt rail support 34 to the respective lading tie anchor27. Here it will be noted that the lading tie anchor 27 has integrallyformed rearwardly extending stops 44 for holding the head 45 of the Huckbolt pin 43 in place. The Huck bolt pin 43 is inserted after welding ofthe lading tie anchor 27 in place in the deformation in the side wall11. When the belt rail support 34 is applied, as shown by the brokenlines in FIG. 8, the Huck bolt pin 43 can be shifted to enter theopening 37 in the belt rail support 34 and then is tightened in place bya suitable tool.

FIGS. and 11 show another manner in which the lading tie anchor 27 canbe modified for subsequent application of the belt rail support 34. Hereit will be observed that the lower end of the lading tie anchor 27 isprovided with a socket 46 for receiving a hexagonal head 47 of a bolt48. It will be understood that bolt 48 is held in place by the socket 46after the lading tie anchor 27 has been welded in position.Subsequently,

after application of the belt rail support 34, a nut 49 between openings53. The belt rail support 34 is provided with outflared wings 54 forinsertion in the openings 53 and against the wedge shaped section 52. Asillustrated in FIG. 12 and shown by broken lines, the belt rail support34 provided with the out flared wings 54 is swung from the broken lineposition to insert the wings 54 in the opening 53. As the wings 54 areswung inwardly in the direction indicated by arrow 55 their distal endsengage the wedge shaped section 52 and, as they move through theopenings 53, they are spread outwardly to provide a friction grip withthe lading tie anchor 27. As shown in FIG. 12 a recess 56 is provided inthe lower end of the belt rail support 34 for receiving a suitable toolto permit removal of the belt rail support 34 provided with the wings54.

In FIGS. 15-18 it will be observed that a vertical groove 57 is formedin the side wall 11 by deforming it into the space enclosed by therespective side post 12. The vertically extending groove 57 provides alading tie receiving section having a bottom wall 58 and inclined sidewalls 59. Located in the groove 57 is a continuous lading tie receivinganchor 60 having spaced wide sections 61 which are welded at 62 to theside walls 59 of the groove 57. The continuous lading tie receivinganchor 60 has spaced narrow lading tie receiving sections 63 aroundwhich the lading tie 31 can be positioned as will be understood readily.

When the continuous lading tie receiving anchor 60 is to mount beltrails 14, belt rail support receiving openings 64 are formed in the widesection 61 for receiving belt rail J-shaped support plates 65 as shownmore clearly in FIG. 17. The support plate 65 has the hook portion 66applied through the belt rail support receiving opening 64. The beltrail J-shaped support plate 65 has outwardly extending side portions 67that are arranged to overlie the lading tie receiving section 63 for thepurpose of resisting longitudinal shock forces applied to the belt rail14. Near its lower end the belt rail support plate 65 has an opening 68for receiving a bolt 69 which may be threaded into a self-locking nut 70that is welded to the rear side of the continuous lading tie receivinganchor 60 before it is installed in the groove 57. It will be noted inFIG. 17 that the nut 70 has a flange 71 which extends into an opening 72in the lading tie receiving anchor 60. This arrangement facilitatesproper location of the nut 70 prior to welding of it in place.Subsequently the continuous lading tie receiving anchor 60 is welded inplace with the nuts 70 in position to receive the bolt 69 for securingthe belt rail support plate 65 in position on application of the bolt69.

The belt rail 14 is welded as indicated at 73 to the front side of thebelt rail support plate 65 and extends along the inner surface of theside wall 11. The belt rails 14 are horizontally aligned on oppositesides of the box car 10 for receiving the cross members 18. If it isdesired to remove the belt rails 14 and the belt rail support plates 65welded thereto, this can be accomplished readily by merely unscrewingthe bolts 69 and removing the assembly to permit use of the lading tiereceiving anchor 60 for receipt of conventional lading ties 31.

Referring now particularly to FIGS. 19, 20 and 21 it will be observedthat the side wall 11 is provided with a vertical arcuate groove 74. Thearcuate groove 74 is formed by deforming the side wall 11 and it will beun' derstood that a number of the arcuate grooves 74 is provided alongthe side wall 11. The groove 74 constitutes a lading tie receivingsection for the continuous lading tie receiving anchor 60. The ladingtie receiving anchor 60 is formed in sections which are welded togetherat 75 and, as previously described, are welded at 62 to the side wall11. As before the narrow lading tie receiving section 73 can be employedfor receiving the lading tie 31 as illustrated in FIG. 3.

It is desirable that the lading tie receiving anchors 60 be providedwith a minimum of adaptation for receiving belt rails. The reason forthis is that there is the possibility that the box car may never bemodified to receive belt rails. Accordingly the wide sections 61 haveformed therein key shaped openings indicated generally at 76 whichcomprise a circular portion 77 and a rectangular portion 78. Infabricating the continuous lading tie receiving anchors 60 it is onlynecessary to punch out the key shaped openings 76 which can beaccomplished readily in their formation. Then it is unnecessary toprovide an additional element, such as the self locking nut 70, FIG. 17,which may never be employed.

It will be understood that the box car is built with the side walls 11in place having the vertical arcuate grooves 74 therealong. The sectionsof lading tie receiving anchors 60 are welded in place at 62 with thekey shaped openings 76 in the wide section 61 thereof.

When it is desired to convert the box car for use with a belt rail,bolts 79 are applied. Each bolt 79 has a round head 80 of such diameterthat it can be inserted edgewise through the circular portion 77 andrectangular portion 78 of the respective key shaped openings 76. Then,as shown in FIGS. and 21 a square shank 81 of the bolt 79 can interfitwith the rectangular portion 78 of the key shaped opening 76 so as tohold the 'bolt 79 against turning. The shank 81 of the bolt 79 isarranged to extend through a transverse elongated opening 82 in a bottomwall 83 of an intermediate offset section 84 which forms a part of abelt rail support as indicated, generally, at 85. It will be observedthat the belt rail support 85 is generally hat shaped and it will beunderstood that it extends in overlying relation along the lading tiereceiving anchor 60 to the to the extent desired depending upon thenumber of belt rails 14 that are to be employed. The belt rail support85 has oppositely extending flanges 86 which are welded at 87 to thebelt rail 14. The square shank 81 of the bolt 79 extends through acircular washer 88 which has a sufficient diameter to overlie theelongated opening 82 and a nut 89, threaded on the shank 81, can betightened to hold the belt rail support 85 in place.

It will be understood that the belt rails 14 can be assembled on thebelt rail supports 85 by welding thereto as indicated at 73. Then theassembly can be applied to the lading tie receiving anchor 60 andsecured thereto by the bolts 79 in an obvious manner.

Referring now particularly to FIGS. 22, 23 and 24 it will be observedthat a belt railangle 90 is employed as an alternate to the belt rail 14previously described. In connection with the belt rail 90 there isprovided a belt rail support that is indicated, generally, at 85 It isessentially the same as the belt rail support 85 except that itsintermediate offset section 84' is slightly shallower. The belt railangle 90 comprises a downwardly extending flange 91 that is welded at 92to the oppositely extending flanges 86. Also it includes a horizontalflange 93 that is provided with apertures 94 to receive locating pins ofcross members which are similar to the cross members 18 previouslydescribed.

FIG. 24 shows how a Huck bolt pin, indicated generally at 95, can beemployed in lieu of the bolt 79. The pin 95 is provided with a roundhead 96 and a round shank 97 which extends through the rectangularportion 78 of the key shaped opening 76. Also it extends through thetransverse elongated opening 82 and the washer 88. A sleeve 98 isdeformed unto the round shank 97 in accordance with conventionalpractice.

FIG. 19A shows key shaped opening 76' in the anchors 60 in oppositerelation to upper key shaped opening 76. The circular portion 77 isbelow the rectangular portion 78'. With this arrangement of the keyshaped openings and the square shanks 81 of the bolts 79 in therectangular portions 78 and 78', the belt rail support is held againstvertical movement in either direction which might occur should the bolts79 become loose or sufficient upward force be applied to the arrangementshown in FIGS. 19, 20 and 21 to shift the bolts 79 out of the key shapedopenings 76 all disposed in the same direction. The key shaped openings76 and 76 can alternate along the anchors 60.
